Imagine three people huddled in a circle so when one speaks, only one other hears. Scientists have created a device that works like that, ensuring sound waves ripple in one direction only. The device, ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

In our everyday world, waves are stubbornly democratic. Whether it’s the sound of a conversation, the glow of a lightbulb, or ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...

Sound spreads both forwards and backward in a space, meaning someone standing nearby can hear you as well as you can hear them (even if you'd rather they couldn't). A team of researchers has found a ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

NASA has recently transformed sound waves emanating from the Perseus Galaxy Cluster’s black hole into a format perceptible to ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Scientists at Japan’s Nagoya University have used Japan’s extensive network of GNSS receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake.
